"The Sink and Float of Materials in Water" Materials Around Us PPT Courseware 2

think about it

1. How to judge the sinking and sinking of materials? How to calculate weight?

If the object touches the bottom of the tank downward, it means that it sinks in the water. If the object cannot touch the bottom of the tank, it means that it floats in the water.

All reasoning must be derived from observation and experiment. ——Galileo

Experimental requirements

1. Fill in the experiment record form, predict first, then experiment, and keep records. (Sink and float means)

2. Test the materials one by one in order. After testing one material, take it out and then test the next material. The same item should be tested at least three times.

3. When doing experiments, students are asked to gently put it in the middle of the water to prevent water droplets from splashing on the table.
